[Intel-gfx] [PATCH 07/18] drm/i915/bxt, glk: Give a proper name to the power well struct phy field

[Imre Deak]

Follow-up patches will add new fields to the i915_power_well struct that
are specific to the hsw_power_well_ops helpers. Prepare for this by
changing the generic 'data' field to a union of platform specific
structs.
